NETWORK SYSTEM, PACKET FORWARDING APPARATUS, AND METHOD OF FORWARDING PACKETS
First Claim
1. A network system comprising:
- a first network;
an authentication server configured to execute an authentication process when a terminal apparatus joins the first network;
a second network to which the authentication server is connected;
a third network to which the terminal apparatus and the authentication server are not connected; and
a packet forwarding apparatus being connected to the first network, the second network, and the third network, and forwarding packets,wherein the packet forwarding apparatus includes;
a forwarding route table storage storing a first forwarding route table that contains packet routing information to a prescribed device connected to the second network, and a second forwarding route table that contains packet routing information to a prescribed device connected to the second network and packet routing information to a prescribed device connected to the third network; and
a forwarding route table selector that, prior to determination of successful authentication for the terminal apparatus by the authentication server, selects the first forwarding route table as a search forwarding route table that is used for searching for a packet routing information applied to packets from the terminal apparatus, and that upon receipt of determination of successful authentication for the terminal apparatus by the authentication server, selects the second forwarding route table as the search forwarding route table.
